APPARATUS FOR CLEANING OIL WASTIEl.

Specification of Letters Patent.

' Patented Got. 12:, 1909.

Application filed July 17, 1908. Serial No. 444,123.

To all whom it may concern:

Be it known that we, JACOB I. ORKIN and United States, residing at Boston, in the county ofSuffolk and State of Massachusetts, have invented certain new and useful Improvements in Apparatus for Cleaning Oil-VVaste, of which the following is a specification, reference being had therein to the accompanying drawing.

Our invention-relates to improvements in apparatus forcleaning: oil waste, in which means are provided for extracting oils, grease, gums and other substances from cotton and other waste by the application of steam or volatile solvents, the substances when properly extracted, being suitableto be used for the same pur oses as formerly, and, the cleansed waste a ter being suitably dried, being nearly as good as new.

The object of the invention is to provide a machine of comparatively few parts, simple in operation and provided with a steamtight cover easily removable.

The invention consists in the combination of elements and in certain parts of novel construction entailed in the combination of said elements to obtain the desired result.

A full understanding of our invention can best be given by a detailed description of a preferred construction embodying the various features of our invention, and such a description will now be given in connection with the accompanying drawings, and we attain our object by the mechanism there illustrated, showing such preferred construction, and the features forming the invention will then be specifically pointed out in the claims.

.In the accompanying drawings, Figure 1 is a central vertlcal section of our im roved apparatus. Fig. 2 is a plan view of tih per portion of the machine, partly in section. Fig. 3 is a side elevation of one of the cover-clamps. Fig. 4 is a front elevation of one of the cover-clamps with the handle extended.

Latitude is allowed hereinas to details, as they may be changed or varied at will without de arting from the spirit of our invention and the same yet remain intact and be protected.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

opposite side of the tank: .may be provided in the bottom 6 for drawe up-.

In the drawings 1 indicates a steam tank, which is a cylindrical metal receptacle supported by legs or tached to a base-plate 3. The tank is provided with a steam inlet-pipe 4, having its entrance near, the top of the tank, and an outlet-pipe 5, which is located at the bottom of the tank adjacent to the bottom 6, on the A drip-cock 7 ing off the substances separated from the waste, and the water for washing the waste. The tank 1 is provided with a cover 8, having handles 9, and provided with slots or openings 43 around its adapted to engage and receive links 10 of cover-clamps 13. The cover-clamps 13 are provided with rounded base-portions 11, which afl'ord means for readily and quickly clamping and unclamping the cover-clamps by lowering or raising the cover-clamps 13, thus dispensing with bolts or screws in clamping the cover down upon the steam tank. The cover-clamps 13 at their baseportions 11 are pivoted to brackets 12, attached to the surface of the tank 1, at the upper end of a link 10 by a studpin 40, thelower end of the link 10 bein ivoted to the bracket 12 by a stud 4.1, an eing threaded and provided with nuts 14, so as to rovide means for adjusting the pressure of the cover-clamps upon the cover 8.

The circumference of the tank 1 is provided with a receptacle 15 flush with the ed e of the tank and adapted to receive and hoTd a suitable packing-ring 16, which projects somewhat above the edge ofthe tank 1 and provides, when the cover 8 is clamped down by the cover-clamps 13, a steam-tight joint between the cover 8 and the edge of the tank 1. A cross-brace 17 extends across the top of the tank 1 just below its edge, to which is attached. at its center a bearing-case 18 provided with roller-bearings 19, which come in contact with the shaft 20. 7 Within the tank 1 is a perforated, cylindrical drum 21, its wall having a series of openings 22 and its bottom 23 also being provided with openings 24. A cross-brace 25 is attached to the top of the drum 21 and below its edge, and is provided at its center with a boss 26, which serves to hold the shaft 20 in position.

The shaft 20 connects the cross-braces 17 and 25 by connecting\ the bearing-case 18 and the boss 26, the s aft 20 being held 1n standards 2, which are at-' circumference,

\ the boss 26 by a set-screw 27 and left free to revolve in the bearing-case .18 against the rollerbearings 19. A boss 29 is attached to the bottom 23 of the drum 21 at its center.

A shaft 30 rotated by the pulley 31 is held in the boss 29 by a set-screw 32. A hearingcase 33 is attached to the bottom 6 of the tank 1, beingprovided with roller-bearings 34, whichcome in contact with the shaft 30 and a packing-case 35, which is provided with adjustable means 36 for taking up the wear in the packing.

In the center of the base-plate 3 is placed a bearing-case 37 provided with roller-bearings 38 and ball-bearings 39. The shaft 30 assing through the bearing-case 33 revolves reely against the roller-bearings 34: of the bearing-case 33, the end of'the shaft 30 restin the bearing-case 37 while the shaft revolves freely against the roller-bearings 38 of'the bearing-case 33.

In operation the waste to be cleaned is placed in the drum 21 and the cover 8 fastened securely down by the cover-clamps 13.

Steam is then admitted to the tank 1 by the inlet-pipe i and passes through theperforations 22, 24 into the drum 21 andjthrou h the waste. The shaft 30 is then revolved %y the pulley 31, which is connected'to any suitable power. When sufliciently treated the oily substances are removed from the waste and pass through the perforations into the tank 1, from which they may be drawn off as desired, through the drip-cock 7. When the oily substances have been withdrawn, the tank may be filled with water and the waste thoroughly washed and cleaned.

It is to be understood that our invention 'is not limited to the specific details of construction shown in the accompanying draw ings, but that said details may be varied in the practical carrying out of our invention. It is also to be understood that the combinations specifically set forth in the several claims are intended to be separately claimed without limitation to the use in connection therewith of other features and details of construction illustrated.

Having thus described our invention, we claim as new and desire to secure by Letters Patent- 2 1. In an apparatus for cleaning oil waste, the combination with a stationar steam tank, of a cylindrical drum revolub etherein, perforations in the side and bottom of said drum, a steam inlet-pipe located in the side of the said tank, a steam-tight cover for said tank, and a divided shaft, having its upper portion mounted in a cross-brace extending across the top of the said drum and seated in a bearing case mounted on a crossbrace extending across the top of the said tank and having its lower portion attached to the base of, said drum and seated in a bearing case centrally mounted in the baseplate. I

2. In an apparatus for cleaning oil waste, the combinatlon with a stationary steam tank, of a cylindrical drum revoluble there in, perforations in the side and bottom ofsaid drum, a steam inlet-pipe located in the side of the said tank, a steam-tight cover for said tank, a plurality of cover clamps having rounded base portions attached to the upper edge of said tank and adapted to register with slots in the circumference of the said'steam-tight cover, and a dividedv shaft, having its u per portion mounted in a cross-brace exten mg across the top of the said drum and seated in a bearing case mounted on a cross-brace extending across the top of the said tank and having its lower portion attached to the base of said drum and seated in a bearing case centrally mounted in the base-plate.

In testimony whereof we afiix our signatures in presence of two witnesses.
